Do ghosts make a room colder? Many paranormal reports say yes. The measured evidence says something more careful. Most cold spots people feel are not matched by a thermometer reading, and the ones that are measured usually have ordinary causes. A real temperature drop can still be worth documenting. You just need the right gear and a method that rules out the boring explanations first.
This guide covers the claim, the research, the body’s role, and a field method for logging cold spots you can trust.
TL;DR
- A cold spot is a sudden feeling or reading of cold, often tied to ghost reports. Measured proof is thin.
- In an Edinburgh vault study, about 44% of participants reported haunt experiences, yet air temperature was not significantly related to them.
- Drafts, cold windows, humidity, fear and suggestion can all make you feel cold with no air temperature change.
- To log a real drop, use a fast sensor, record a baseline, and keep your team blind to where the “cold spot” is supposed to be.
- Treat any drop as data to explain, not as proof of a spirit.

What people mean by a cold spot
A cold spot is a small area that feels much colder than the space around it. Reports often describe a sudden chill, visible breath, or a cold patch that seems to move. The Psi Encyclopedia entry on cold spots notes that sudden cold appears again and again in reports of apparitions, séances and hauntings, and is often treated as a sign of paranormal agency. It also says the instrument-based evidence remains sparse.
The popular theory is that a spirit pulls heat out of the air to build up energy. That idea is common in ghost lore. It is not an established physical mechanism, and nobody has shown it in a controlled test. So the useful question is not “is this a ghost?” It is “what is making this spot cold, and can I measure it?”
What the field research found
Some investigators do report big measured drops. One Pennsylvania team leader told AccuWeather his group has logged drops of up to 10 degrees within seconds. That is a firsthand claim from a practicing investigator, not a controlled study, and it should be read that way.
Controlled work looks different. Parapsychological field investigations at Edinburgh’s South Bridge Vaults found that air temperature was not significantly related to reported haunt experiences, even though nearly 44% of participants reported one. People felt things. The thermometers did not track it.
A primer on temperature in haunting experiences makes a related point. Rare historical reports describe drops of 9 to 10°F, but such drops are often attributable to environmental shifts like settling building materials or thermal contraction. Most reported cold spots do not coincide with a detectable drop when calibrated sensors are watching.

Why you can feel cold when the air is not
This is the part new investigators miss. Your skin does not read air temperature. It reads how fast you lose heat. Several things change that rate without changing the air.
🌬️ Drafts. Moving air strips heat from skin and speeds evaporative cooling. ASSAP explains that a standard air thermometer does not record this as a change in ambient temperature. A draft from a chimney, a gap under a door or a vent can feel like a cold hand passing by.
🪟 Cold surfaces. Stand near an uncurtained window on a cold night and your body radiates extra heat toward the glass. You feel cold in that direction. The room’s air reads normal. The same applies to uninsulated walls and stone.
💧 Humidity. In damp spaces such as cellars and old stone buildings, moisture evaporating from your skin adds to a clammy, chilled feeling.
😨 Fear. Stress can narrow blood vessels near the skin. A review of stress and body temperature shows stress changes how the body regulates temperature. In plain terms, a nervous investigator in a dark basement can get cold hands and an icy shiver with nothing changing in the room. The body’s own heat-saving response is described in a paper on thermoregulation and vasoconstriction. Narrowed vessels protect core temperature but leave hands and feet cold.
🧠 Suggestion. ASSAP stresses that if investigators are told where a cold spot is supposed to be, they are significantly more likely to report feeling one. Tour guides and local legends do this all the time.
None of this proves nothing odd ever happens. It means a feeling alone cannot carry the case.
Why thermometers miss real drops, too
The problem runs both ways. A brief drop can pass before a slow sensor catches it. NIST describes this delay as sensor response, and its materials on choosing thermometer sensor types list platinum resistance, thermistor and thermocouple designs that differ substantially in performance. A cheap or poorly placed probe can smooth over a short dip.
Two practical lessons follow:
- Pick a sensor with a fast response time, and give it time to settle in each spot.
- Do not hold the device against a wall, your hand or a lamp. Keep it in open air, away from your body heat.
A sensor you trust is also a calibrated sensor. Our page on equipment calibration explains what that means and why a reading is only as good as the check behind it.
Air thermometer or infrared: know what you are reading
Two tool types get mixed up constantly.
| Tool | What it measures | Good for | Watch out for |
|---|---|---|---|
| Air temperature sensor or data logger | The air around the probe, over time | Baselines, trends, real drops in a room | Slow response if the sensor is cheap |
| Infrared thermometer | Surface temperature of what it points at | Finding cold walls, windows, floors, draft sources | It does not read the air itself |
| Thermal camera | Surface temperature as an image | Seeing heat patterns across a whole scene | False positives from reflections |
An infrared thermometer is excellent for explaining a cold spot. Point it at the window, the wall and the floor. If the surface is much colder than the rest of the room, you may have found your “ghost.” Our guides on how to use an infrared thermometer and infrared thermometer ghost hunting tips cover aiming, distance and common mistakes.
Thermal cameras show the whole picture at once. They also create their own errors, so read five field checks for thermal camera false positives before you trust a cold shape on screen. If you want to start with the basics, see mastering a thermal camera for ghost hunting.
A field method for logging cold spots
The goal is a record another person could check. Here is a simple routine.
- Walk the site in daylight. Note windows, vents, fireplaces, doors, cracks and plumbing. Mark every likely draft.
- Record a baseline. Take air and surface readings in each room before the investigation starts. Write the time, outdoor weather and whether heating was running.
- Keep the team blind. Do not tell investigators where a cold spot is said to be. As ASSAP advises, let them report first, then compare to the reported locations afterward.
- Use fixed sensors. Place air sensors at set heights in set spots, away from people. Handheld readings are useful, but a fixed logger shows what happened when nobody was looking.
- Log timestamps. Note the exact time of every felt chill. Later you can match it to the sensor data.
- Check the dull causes. When a reading drops, test the nearest window, vent and wall with an infrared thermometer. Turn off nearby fans. Check whether a door opened.
- Repeat the test. If the spot returns at the same place and time with no draft or heating cycle, note it. If it never repeats, say so.
A multi-sensor logger makes steps 4 and 5 much easier. Our guide to environmental data loggers for ghost hunting shows how to sync every channel on one timeline.
Reading the numbers
A few rules keep you honest.
- A slow, steady fall over an hour usually tracks the heating cycle or the night outside.
- A drop that lines up with a door opening or a fan switching on is a draft until shown otherwise.
- A sharp drop of several degrees in open air, away from every vent, with a calibrated and fast sensor, is worth flagging. It is still not proof of a ghost. It is an unexplained reading.
- If only one sensor shows it, suspect the sensor. Two independent sensors showing it is stronger.
Cold spots in games are not field data
Some of the top search results for this topic are about the game Phasmophobia, where ghost types have different temperature rules. A fan-run GitHub breakdown describes how the game makes rooms drop to set temperatures and adds randomness to the in-game thermometer. That is game design. It says nothing about real buildings, so do not use it as a benchmark for what a real thermometer should show.
Our view: measure first, then wonder
We are an independent affiliate resource, and our focus is simple: help investigators get good data and stay safe. A cold spot is the most talked about sign in ghost hunting, and also the easiest to fool yourself with.
Here is where we land. Treat the feeling of cold as a prompt, not a finding. The most interesting cold spot is one that survives your own attempts to explain it away. That means a baseline, a blind team, two sensors and a check of every window and vent. If it still holds, you have something worth writing up honestly, including the part where you cannot explain it.
For gear, we lean toward a fast air sensor or logger first and an infrared thermometer second. The logger tells you what the air did. The infrared tool tells you why it might have felt cold. A thermal camera is a strong third tool once you understand its false positives. We would rather you spend on one reliable sensor than five gadgets that disagree with each other. Safety counts too: unstable floors, cellars and abandoned buildings are bigger risks than anything paranormal, so get permission and never go alone.

FAQ
Why do spirits make you feel cold?
The traditional idea is that a spirit draws heat from the air. There is no tested mechanism behind it. Drafts, cold windows, damp air and a fear response can all make you feel cold with no change in air temperature, so check those first.
Can a thermometer prove a ghost is present?
No. A thermometer records a number, not a cause. A drop that repeats, shows on two sensors and has no draft, vent or heating explanation is an anomaly worth logging. It still falls short of proof.
How big does a temperature drop have to be to count?
There is no accepted threshold. Historical reports mention drops of 9 to 10°F, but these are rare and often linked to building materials settling or contracting. Compare any drop to your baseline and to the normal swings of that room.
Should I use an infrared thermometer or an air thermometer?
Use both for different jobs. An air sensor or logger records the air around it. An infrared thermometer reads surface temperature, which helps you find cold windows, walls and draft sources that explain a chill.
Why do I get cold when I am scared?
Stress can narrow blood vessels near the skin, which leaves hands and feet feeling cold. This is a normal body response, and investigators often mistake it for a cold spot. If you feel unwell or very cold for long, step outside and warm up.
